I was just wondering if it would be illegal for me to get a k20a2 into my 2001 civic ex. I was wondering this because they told me that if i do this engine swap my car wouldn't be able to pass the smog test. Is this true or not?

false. completely legal as long as you have the right equipment (oem spec, factory cat)

as long as the engine you are putting in ur car is newer then than the year of the car.

if the rsx-s can pass smog, i dont see why not.

yes, stl01civic is right, any motor/engine that is older than the car itself is illegal to swap in. with an k20a2 in your civic, i wouldnt leave any bolt-on mod on the car when smogging it for safety reasons. i would use 100% OEM parts

about the older engines part, it is mostly bs around here unless you are trying to sell the car. then thats when its illegal.

false, they cannot do that.... just do it right. or do it other way, smog test first then do the swap.
